FDXT: Forward and Backward Private Conjunctive Searchable Encryption to Suppress Volume Leakages Caused by Cross-Tags
- Published
- Record updated
Summary
FDXT is a new conjunctive dynamic searchable symmetric encryption scheme that guarantees forward privacy for all queried keywords in a multi-keyword search, whereas ODXT only protects the single first queried keyword. It also avoids the volume leakage that SDSSE-CQ suffers from, and experiments on the Crime, Wikipedia and Enron datasets show performance comparable to ODXT and significantly better than SDSSE-CQ.
